BOTTLE-TAP? SPECIFICATION forming part of Letters Patent N o. 718,163,dated January 13, 1903.

Application filed October 17,1902. Serial No. 127,709. (No model.)

T0 @ZZ zu17/1,0717, it may concern:

ABe it known that I, JOSEPH ALFRED SHER- RARD, of Boston, in the countyof Suifolk and State of Massachusetts, haveinvented certain new anduseful Improvements in Bottle-Taps, of which the following is aspecification.

This invention has for its object to provide a simple and efficientmeans for tapping closed or corked bottles or other receptaclescontaining liquids and also for creating an air-pressure within thebottle to facilitate the discharge of the liquid therefrom.

The invention consists in the improvements which I will now proceed todescribe and claim.

Of the accompanying drawings, forming a part of this specification,Figure l represents a sectional view of my improved bottle-tap and aportion of a bottle in which the same isinserted. Fig. 2 represents aside elevation of a portion of the tap and of the bottle-neck. Fig. 3represents a view similar to Fig. l, showing a modification. Fig. 4represents a view similar to Fig. l, showing the tap made on a largerscale and provided with an extension adapted to reach to the bottom of abottle or carboy. Fig. 5 represents a View of aportion of theconstruction shown in Fig. 4.

The same reference characters indicate the same parts in all thefigures.

My improved bottle-tap comprises a rigid tubular conduit a, the innerportion of which is formed to penetrate abottle-stopper, said innerportion having a penetratingpoint 2 and a helical cutting-rib orscrew-thread 3. At the outer end portion of the conduit a is a cock 4,adapted to open or close the liquid duct or passage 5, which extendsthrough the conduit. The conduit a is provided between the cock 4 andthe penetrating portion with a branch 6, containing a spring-pressedairvalve 7. Said branch, as shown in Fig. 1, communicates with anannular air-duct 8, surrounding the liquid-duct said air-ductcommunicating with the interior of the bottle through one or moreopenings 9. As shown in Fig. 3, the branch 5 communicates with theliquid-duct 5.

b represents an airpump which is connected with the branch G and isadapted to force air through the latter, the valve 7 yielding to permitthe entrance of air fromthe pump and closing automatically to preventthe backward passage of air from the branch to the pump. The pump may beof any suitable construction, it being here shown as a lcollapsibleelastic bulb, such as is used for syringes. It is obvious, however, thata pump similar to that used for intlating bicycle-tires may be employed,if desired. It will be seen that when the pump is operated to force airthrough the branch 6, the cock 4 being closed, the air iinds its wayinto the interior of the bottle and exerts pressure on the contentsthereof. When the cock 4 is opened, the airpressure forces the liquidthrough the duct 5, the valve 7 preventing the escape of liquid throughthe branch 6. It will be seen, therefore, that the described tap havingprovisions for accumulating air-pressure in a bottle may be used to goodadvantage in drawing bottled liquids of various kinds, eithereffervescent or still, and particularly useful in drawing,

champagne or other eervescent liquid, the pump being operated after agiven quantity of the liquid has been withdrawn and creating freshpressure, so that another charge maybe caused to iiow rapidly from thebottle.

The conduit is provided with a rigid flange or shoulder a, between whichand the top of the stopper is interposed a compressible pack ing-washerof", which prevents the escape of gas or air under pressure from theinterior of the bottle.

In Fig. 4 I show a construction similar to that shown in Fig. 1,excepting that the penetrating-point 2 is made separable from the bodyof the conduit, the lower end of the liquid-duct 5 being extended andprovided with a screw-thread, to which may be coupled an extension 12,adapted to extend to the bottom of a bottle or carboy.

My improved tap will draw contents from any bottle, whether the liquidis aerated or plain. The said tap is adapted to aerate a bottle of ale,beer, porter, or similar liquid, so that the bottle may be opened, apart of contents used, and the remainder allowed to stand indefinitelyand be drawn owhen required, when contentswill be found in as goodcondition as when first tapped. In fact, the bottle may be opened and aglass or more of the liquid used. The cork may then be replaced, andwhen the remainder of the con- IOO tents are required the tap may bescrewed into the cork, pressure applied, and the contents will be foundin as good condition as the first glass.

time?,

leading from the conduit intermediate of said cock and pointed end, aange or shoulder formed on said conduit, a compressible packing-Washerlocated below said ange, and an air-pump connected to said branch andadapted to force air into the conduit, the said cock when closed causingthe air to enter the bottle and act upon the contents thereof, and whenopen permitting the discharge of said contents through the conduit.

In testimony whereof I have affixed my signature in presence of twowitnesses.

JOSEPH ALFRED SHERRARD.
